Commercial and Industrial Roofs Waterproofing in Karachi
Engineered waterproofing for factories, plazas, hospitals, banks, schools and large industrial roofs.
Commercial and industrial buildings need dependable roofs. We have waterproofed large roof areas for factories, offices and institutions, using systems that are tough, quick to apply and easy to maintain.
Problem: why commercial and industrial roofs waterproofing is needed
Large roofs carry plant equipment, AC units and foot traffic. Heavy use damages thin coatings, and drainage problems cause ponding which accelerates failure.
- Repeated leaks after earlier patch repairs
- Ponding water around AC units and drain points
- Blistered or cracked old bitumen
- Damage to false ceilings and electrical systems

We design the system for traffic and weather: reinforced membranes, protected walkways, correct drainage details and a heat reflecting finish.
